WINDOW SHIELD Filed May 15, 1942 INVENTOR 'OLIVER E.SCHIRRA ATTORNEYS "ventilator window,

1 and backwardly slanting portion of the window -will be forced against the air by the velocity of Patented July 25, 1944 U IT D STATES PATENT OFFICE OliverE.scm'mzfzthaono 2 Claims. 352x4 7 This invention relates to window shields, and more especially it relates to such a shield adapted to be attached to the outside surface of the glass window frame whereby it may be turned transversely of its frame in such manner that its front edges extend into the automobile body and its rear edge extends outwardly from the'said body. When the window is in this transverse position and the automobile is driven forward at a time there is no side wind blowing there will be a flow of air out of the automobile body through the The outwardly extended the -automobile in its forward direction. The air will be setin motion and will be deflected outwardly as will be readily understood. This makes it possible for the occupants of the front seat of a sedan type of automobile or the occupants of a coupe type to open a front ventilator window while the automobile may be traveling at a high rate ofspeed without a strong rush of air inwardly through the open window, thus aifording themselves fresh air without the inconvenience of a strong draft or wind striking them.

However, these ventilating windows are not comlator windows, if opened as described above, permit the rain that falls on the inwardly and forwardly turned portion of the pane to move forwardly on the glass until the water drops from the bottom of the pane or its channel member into the automobile where it wets the upholstery or it may fall upon the legs of the driver making him uncomfortable and distracting his attention from driving, which, of course, may cause him to lose control of the automobile.

This invention has as one of its objects to provide means for intercepting water that may reach the inside of an automobile body on a ventilator window pane and for discharging such water outside the automobile.

Another object of the invention is to provide such water-receiving means of a type that can be conveniently attached to the ventilator windows of automobiles now in use as well as to the windows of automobiles in the process of being man ufactured.

Other objects and advantages of the invention will be manifest to those familiar with the art by reference to the accompanying drawing, where- Flg. 1 is a perspective view of the device embodying the invention and in operative position on a ventilator window;

Fig. 10 is a sectional view on line Ill-ll of Fig. 1;

Fig. 11 is a sectional view of another form of the invention wherein the channel member is formed to provide a groove.

The shield embodying the invention is here illustrated as molded and composed of rubber. However, it is to be understood that any other satisfactory moldable material maybe used or it may be fashioned from metal or wood or thelikc.

By reference to the drawing it will be seen that in one form the invention consists of a shield l0 having an upwardly turned end or head portion II and an elongated tapered body portion H. The shield is attached to the pane of the ventilator window in operative position as shown in Fig. 1. While the shield may be placed in a slanting position in order to give more fall to water it may be draining, I have found that this is not necessary due to the bottom of a groove G being higher in its turned up portion and being open at its tapered end. Thus by reference to Figs. 4, 5, 6, and 7 it will be seen that the groove G has a rear side IS, a front side It, and abottom side 20, and that the said groove progressively changes its size and contour until it opens at approximately section 1-4 of Fig. 2 where the front side It terminates in a substantially abrupt tapered end, the rear side l3 continuing a distance beyond the end of side It and terminating in a slightly raised transverse end portion l5. This end portion acts as a bame to the flow of water emerging from the groove G and assists in discharging the water from the shield. The inner side of the end portion I5 is formed with a radius in order that it will be more effective in turning water. The attachment of the shield to the pane of glass may be done by adhesion or by any other method found satisfactory. In the event the shield is composed of soft rubber, I have found that a cement such as that being commercialized by Henry G. Lange Machine Works of Chicago under the trade name Superior provides a satisfactory bond between the rubber of the shield and the glass of the window. It is to be noted that the rear side I: has sufficient width and length to present a relatively large contact area to a window pane. Of course the rear side of the shield may be dispensed with as the glass against which the .shield is placed will take the place of the side I! in forming the groove G except for the transverse portion II, which portion may be formed on the end of the bottom" as will be understood by those familiar with the art. To facilitate the attachment of the shield to the window pane the shield may have a "backing" of adhesive material applied to the attaching face of the side It. In the case of a soft rubber shield, the attaching face may be buffed, cemented, and a backing of unvulcanized rubber on holland cloth may be applied so that when the shield is to be applied the holland cloth may be removed exposing a fresh tacky surface for contact with the pane or toreceive additional adhesive applications. If the design of the ventilator window is such that its channel member in which the pane is held has sufllcient area on its side to receive the shield, the shield may be attached to the channel as obviously it would function in that position. Th embodiment of the invention as shown in Fig. 1 is for the left window of an auto mobile and could not be used on a right window. However, a universal shield may be designed by forming the side ll to be the same as the side H and such modification is to be considered to come within the scope of this invention.

A modified form of the invention is shown in Fig. 8 wherein the rear side I! of the formv of the invention shown in Fig. l is omitted and a partition strip II is employed. This partition strip extends from a front side Ila to overhang a bottom portion Ila and is substantially parallel to it. Thepartition 2| terminates at its forward end so as to provide an opening 22 between its end and the raised head portion Ila. This opening 2! permits water to pass under saidpartition 2| alongbottom portion 20a to a discharging point near an end portion ISa. It will now be seen that when a shield of this form is attached to a pane that theedge 23 of the portion II will contact the glass just as the edge of the bottom portion 204: does (see Fig. 9) and that a passageway having water receiving and discharging ends is provided. Under some conditions of service this passageway adds to the efilciency of the shield. A scientific explanation of the factors entering into the operation of this form of the invention, or the form first shown, or the other forms which may come within the spirit of the invention will notbe attempted because of the many variables and the uncertain behavior of water on glass subjected to a moving gas. Whatever a true explanation of the behavior of the water on the ventilator window of the type her involved is, it is'a fact that rain falling against the glass of such window often flows forward when the ventilator is in nodraft" operative position and then downwardly where it drops of the lower forward edge of the glass or its channel member. 'This flow of water is probably due to a partial vacuum being created behind the glass of the window-causing air from outside the automobile to fiow along the forward surface of the glass into the automobile body. When th shield involving this invention is in position it intercepts the water in its grooves along which the water flows until it is caught by the strong backward pressure of the wind pressing against the outwardly and backwardly slanting portion of the ventilator window as the automobile travels forwardly in service.

Another form of the invention is illustrated in Fig. 11 wherein achannel member 30 in which the pane ll of 'a no-draft automobile ventilator window is held has an extendedportion 32 so shaped as to form a groove 33. The groove 3! involves that portion of the channel which lies adjacent to the shield III in Fig. 1, it being understood, of course, that if the groove 33 is formed in the said channel that such groove will function in the same manner as the groove G of the shield l0 and that the special channel replaces such shield.

Although more than one form of the invention has been illustrated and described in detail, it will be apparent to those skilled in the art that various modifications may be made without departing from the spirit of the invention and it is to be limited therefore only by the prior art and the scope of the appended claims.
